Overview

ASTM D561-82(2020) - Standard Specification for Carbon Black Pigment for Paint establishes comprehensive requirements for carbon black pigment used in protective and decorative coatings. Published by ASTM International, this standard details both the manufacturing and the performance characteristics of the pigment, ensuring its suitability for a wide range of industrial and commercial applications. The specification defines the methods for testing, sampling, and evaluating the pigment to guarantee consistency, safety, and performance in end-use scenarios.

Key Topics

• Scope of the Standard: Focuses exclusively on carbon black pigments produced from either natural gas (Type I) or oil (Type II), used in paints and coatings.
• Material Properties: Addresses crucial properties including ash content, acetone extract, moisture (heating loss), coarse particle content (sieve residue), and absence of organic dyes.
• Testing Methods: Specifies ASTM-approved test methods for solvent extractable material, color and tinting strength, ash content, moisture loss, and sieve residue to ensure pigment quality.
• Sampling Requirements: Outlines detailed procedures for random sampling from production batches to ensure product consistency and quality control.
• Agreement and Customization: Allows for mutual agreement between purchaser and seller on certain property limits, such as ash content or moisture, depending on end-use needs.

Applications

The ASTM D561-82(2020) standard is vital for manufacturers, suppliers, and users of paint materials who prioritize performance and quality. Practical applications include:

• Production of Protective Coatings: The specified carbon black pigment is commonly used in paints designed to offer corrosion, weather, and chemical resistance for industrial and architectural structures.
• Decorative Paints and Finishes: Provides deep, uniform black tones and desired tinting strength for automotive finishes, consumer goods, and interior or exterior decorative paints.
• Quality Assurance in Manufacturing: Ensures the pigment meets strict requirements for consistency, safety, and functional properties, reducing the risk of product failure.
• Regulatory Compliance: Adoption of this standard demonstrates alignment with internationally recognized principles on standardization, helping businesses meet export and regulatory requirements.

Related Standards

To ensure comprehensive quality assessment and compliance for carbon black pigment and other paint components, consider the following related ASTM standards:

• ASTM D305: Test Method for Solvent-Extractable Material in Black Pigments.
• ASTM D387: Test Method for Color and Strength of Chromatic Pigments with a Mechanical Muller.
• ASTM D1506: Test Methods for Carbon Black – Ash Content.
• ASTM D1509: Test Methods for Carbon Black – Heating Loss.
• ASTM D1514: Test Method for Carbon Black – Sieve Residue.
• ASTM D50: Test Methods for Chemical Analysis of Yellow, Orange, Red, and Brown Pigments Containing Iron and Manganese.

By adhering to ASTM D561-82(2020) and these related standards, organizations can provide assurance of product consistency, optimize paint performance, and maintain competitiveness in global markets for coatings and colorants.
